I have one eyebrow higher than the other before Botox.Now 7 days in one is really high! Advice? (photo)

It can take up to 2 weeks for Botox to fully kick in. I would give it another week. If the asymmetry still exists then it can be further corrected by adding a little more Botox to the elevated eyebrow. Best wishes.

This should be relatively straightforward to improve.  I recommend injecting a small amount above the right brow, which will help.  

This is called the Mephisto effect. The region of forehead muscle above your right brow is still very active, while the rest is relaxed. This has lead to the peaking of the brow when you animate. A couple more units of botox will correct this fairly quickly.

Botox is not laser precision. Based on experience and the patient's anatomy, a reasonable dose is placed evenly and then there is a small degree of 'spread'. It doesn't always come out 'perfect' regardless of whether you went to a board certified dermatologist/plastic surgeon/generalist or to a qualified nurse injector, I guarantee you they all correct for this. In other words, it is not bad technique per se.

The worse problem to have is for too much to be placed in this region, which can result in brow ptosis (dropped brow) for which little can be done other than waiting for the effect to lessen. 

Best,
